I've posted before about clutch slipping after replacing all of my clutch plates. DP clutches Kevlar frictions and steels. Now I've replaced my diaphragm spring with rivero primo, and I've been using 20 50 synthetic Mobil 1 v twin and it's still slipping when it gets warm. It's an 03 xb9s with an 05 1204cc engine. I'm at my wits end with this thing. I need some answers if anyone can help.
